The invention discloses a red light running early warning method. The method comprises the following steps: acquiring the position and motion state information of a vehicle based on a positioning system and a CAN signal; screening the MAP message set based on the vehicle positioning information, and removing redundant data; acquiring specific position information of the vehicle in a map based on the MAP message set, and detecting the position of a stop line; screening the SPAT message set according to the position of the vehicle in the map, removing redundant data, and further screening corresponding signal lamp phase information; and making a decision according to the obtained signal lamp phase information to judge whether the risk of running the red light exists and giving a prompt. The invention further discloses a corresponding system and a storage medium. By implementing the red light running early warning system based on the V2X Internet of Vehicles technology under various weathers, the accuracy of red light running judgment is improved, and the safety of driving at the intersection is improved.
本发明公开了一种闯红灯预警方法,包括:基于定位系统和CAN信号获取本车的位置和运动状态信息;基于本车定位信息对MAP消息集进行筛选,去除冗余数据;基于MAP消息集获取车辆在地图中的具体位置信息,并进行停止线位置的检测;根据车辆在地图中的位置筛选SPAT消息集,去除冗余数据,并进一步筛选相应的信号灯相位信息;根据获取的信号灯相位信息进行决策,以判断是否存在闯红灯的风险并进行提示。本发明还公开了相应的系统及存储介质。实施本发明,可以在各种天气下基于V2X车联网技术进行闯红灯预警系统,提高了闯红灯判断的准确性,提高了交叉路口行车的安全性。
